摘要
运用解析和数值计算两种方法,分析了各种摄动源对地球静止轨道(GEO)卫星弃置轨道近地点高度变化的影响,得到了近地点高度的变化规律。利用二阶日月引力摄动可造成GEO卫星弃置轨道近地点升高的特点,提出新的卫星离轨策略,在不满足机构间空间碎片协调委员会(IADC)"空间碎片减缓指南"中,GEO卫星弃置轨道偏心率小于0.003要求的情况下,还可以保证卫星不再进入GEO保护区域。
All perturbations to GEO satellite disposal orbit are analyzed by using both analytical and numerical methods and the result of variation in perigee height of GEO satellite disposal orbit is given. With the character of 2nd order lunisolar perturbation,a new de-orbiting strategy is pro- vided, which can ensure that the GEO satellite protected region will not be penetrated. Especially the de-orbiting strategy is applicable to the case that the disposal orbit eccentricity does not meet the requirement of GEO satellite disposal orbit as specified in IADC guideline.
